摘要
高速公路互通式立交的设计方案受多方面因素影响,各因素之间具有强相关性。基于此,梳理构建互通方案评价指标体系,应用网络层次分析法建立实际工程互通式立交设计方案ANP网络模型,借助Super Decisions超级决策软件求解超矩阵和极限超矩阵,获得设计方案综合排序,可以为方案设计提供决策依据。结果表明,网络层次分析法可以较的好应用于互通式立交设计方案的评价,具有一定的工程价值。
The design scheme of expressway interchange is affected by many factors,which have strong correlation.Based on this,the evaluation index system of interchange schemes is sorted out and constructed.ANP network model of actual interchange design scheme is established by applying network analytic hierarchy process.Super Decisions super-decision software is used to solve the super-matrix and limit super-matrix,and comprehensive ranking of design schemes is obtained,which provides decision-making basis for scheme design.The results show that the network analytic hierarchy process can be well applied to evaluate the design scheme of interchange and has certain engineering value.
